The “Loss of sync word” (LOSW) condition has been detected at the respective
customer-side SHDSL port of the LTU. This means that the SHDSL segment
between the respective customer-side SHDSL port of the LTU and the next

Actions
For the failed SHDSL segment:
•
Verify the correct routing of interconnecting cables.
•
Verify that the connectors are properly connected at the local and remote
end of the SHDSL segment.
•
Verify that the receiver at the local end of the SHDSL segment (i.e. at the
LTU where the LOSW condition has been detected) functions properly.
•
Verify that the transmitter at the remote end of the SHDSL segment (i.e. at
the next attached SHDSL device) functions properly.
